Grrr. Pascal causes brain damage. Python is exactly like Java
(with the exception of having no primitive types).
These notions should state *what* is being passed. In Pascal,
that's "value of a slot" or "reference to a slot". To be precise,
in Python it is *always* "value of a reference", (think "pointer
value", not "value of that which is pointed to").
For all of Herr Werth's genius, he bamboozled millions with his
little sleight of hand.
